Homework Help: Calculating Resultant Force

  1. Apr 21, 2010 #1
    I'm I on the right track here?

    1. The problem statement, all variables and given/known data
    Determine the resultant force and acceleration for a box of mass 15kg being pushed with a force of 9N and a force of friction 6N acting to oppose.


    2. Relevant equations

    Force = Mass * Acceleration

    3. The attempt at a solution

    Force = 9N
    Resultant Force = 9N - 6N = 3N (is this correct?)

    Mass = 15Kg
    Therefore,

    3 = 15 * A
    A = 3/15 m/s (this can't be right, can it?)

    yes
    Why not? But although your magnitude is correct, your units are off.
